That is disgusting. I would be seeking a refund for that kind of poor quality control. Machine marks withstanding, if they're consistent i wouldn't really mind, but scratches and gouges out of the box (as others have posted) is inexcusable. Might as well go buy from aliexpress or some trash.

From the side view photo it looks like they are tapered – thickest at the back (against the keyboard) and thinner at the front. Is this the case? If they are tapered, is 1.8 cm the thickest or thinnest dimension, and what is the thickness at the other extreme?
